I've stayed in Thailand for a month and checked into over 8 places to sleep and this is by far one of the overall best places.
LOCATION: Located right next to Gateway mall so you can have a variety of food options, shopping, and much more. I ate at the mall a few times a day.
PLACE: Perfect size for a solo traveler or couples. Washer located on the balcony, sofa, TV, bed is comfortable, towels are nice, shower is very nice and yes there is hot water! The bidet is an added bonus.
Must: Go to the pool on the 33rd floor, you will enjoy the infinity pool and the view of Bangkok. Best spot to watch the sunset.
